Mouse Lats2 Knokcout Cell Line-4T1

LATS2, also known as large tumor suppressor kinase 2, is a serine/threonine protein kinase that plays a vital role in various cellular processes. One of the most critical functions of LATS2 is its role in the Hippo signaling pathway, a highly conserved regulatory network that controls organ size by regulating cell growth, apoptosis, and stem cell renewal. In this pathway, LATS2 and its homolog LATS1 phosphorylate and inactivate downstream effectors such as YAP (Yes-associated protein) and TAZ (transcriptional coactivator with PDZ-binding motif). By doing so, LATS2 prevents these effectors from translocating into the nucleus, where they would otherwise promote the expression of genes that drive cell proliferation and inhibit apoptosis. Thus, LATS2 acts as a tumor suppressor, helping to control cell growth and prevent carcinogenesis. In addition to its role in the Hippo pathway, LATS2 is involved in several other cellular mechanisms. It plays a role in mitotic checkpoint control, ensuring that chromosomes are properly aligned and segregated, thereby maintaining genomic stability. LATS2 interacts with other key regulatory proteins, including p53, and has been shown to stabilize this well-known tumor suppressor, promoting its activity in response to cellular stress and DNA damage. Mutations and alterations in LATS2 expression have been observed in various cancers, including breast cancer, gliomas, and hematological malignancies, underscoring its importance as a tumor suppressor. Therefore, understanding the molecular mechanisms by which LATS2 operates is critical for developing therapeutic strategies against cancer and other diseases characterized by dysregulated cell proliferation and apoptosis.
